Abstract (en)
[origin: EP1950048A1] An ink jet printer comprising a conveyor belt unit 106 for transferring a print sheet 2 on a rotating conveyor belt 106a, a resist roller pair 111 and a BU roller 112 for feeding the print sheet 2 while flexing it in the transferring direction, and first and second ink jet head 104a, 104b for ejecting ink toward the print sheet, wherein the ink jet head 104b ejects ink darker in color than ink ejected from the ink jet head 104a. The ink jet head 104b serves to eject ink, that is darker in color than that of the ink jet head 104a, and is located at a position farther than the arriving position of the print sheet 2 when the print sheet 2 is displaced from the conveyor belt 106a in the transferring direction as the elasticity of the print sheet 2 due to flexure exceeds adhesion between the print sheet 2 and the conveyor belt 106a, while the ink jet head 104a is arranged between the ink jet head 104b and the BU roller 112. By this configuration, print quality can be sustained with high speed printing by using an ink jet head and reduction in printer size achieved.
